Is it just me or was the height on these arms shortened a bit?

Hard to tell without a stock one sitting beside it. Looks like a very nice piece.

I would say they look like they have been put on a slim plan,
as the grease fitting is fully exposed in the newer version .
I bought the UMI Perf 64-67 GM A Body Rear Lower Boxed / Adj Upper Control Arms
# 402126 with Greaseable Poly Bushings for my car .

Love them, no wheel hop and they look strong & great .

Yes they have been. We changed them last year because our Roto-Joint now features an external lock instead of an internal lock. We couldn't use the external lock with the larger boxed tubing.

I hope that helps,
